Air Zooka!!

If you want some fun in the office, get an Air Zooka. This is one of the most surprising little science toys you'll get out there. This lil bucket hurls an invisible ball of air at any target. If your good, you can pin point targets at up to 20 feet and really surprise people. It feels like a ghost punching you. Its the best $15 you'll ever spend. ZeroToys also has a few other little gadget toys that are fun. Check them out!
